Do you have a lot of food products that need to be stored in low temperatures?
Try to distribute this food in the refrigerator correctly.
The lower and middle shelves can be completely filled with products.
But you can't do the same with the top shelf. The less food there is, the better.
And in general, if possible, leave this part of the refrigeration unit empty.
Place products on other shelves first.
The fact is that the upper part of the refrigerator has a relatively high temperature.
This is due to the rise of warm air currents upward.
Therefore, food placed in this part of the unit will not last as long as food placed on the middle or bottom shelf.
If it is possible to place products on all shelves except the top one, then do so.
If you still need to use the top shelf, do not fill it completely. And put there products that have the longest shelf life.
For reference
A refrigerator is a device that maintains a low temperature in an insulated chamber.
